  3. During the course of the research, the criterions of the interpolation effect are mean error ( me ), mean absolute error ( mae ), root mean squared interpolation error ( rmse ) and the difference of mean square deviation between the measured and the estimated surface air temperature. the conclusions are as follows : ( 1 ) by contrasting the gaussian weighted model associated with the error modification with the gaussian weighted model, the error modification is proved to considerably ameliorate the precision of spatial interpolation ; ( 2 ) on the base of the gaussian weighted model, taking altitudinal effect into account can reflect the trend in which temperature changes according to the topographic altitude and may ameliorate the precision of spatial interpolation correspondingly and apparently, which indicates that topographical effect on the preciseness of spatial interpolation can not be disregarded in terms of the region with complicated topography ; ( 3 ) the map of daily surface air temperature distribution, using the modified gaussian weighted model a and b, can accurately reflect the temperature - changing - with - topographical - altitude trend. among them, the better is the model a, whose me is below 0. 03 ?

    在此過程中,採用平均誤差( me ) ,平均絕對誤差( mae ) ,插值平均誤差平方的平方根( rootmeansquaredinterpolationerror ,簡稱rmsie ) ,插值前後測站要素值的均方差( meansquaredeviation ,簡稱msd )差值作為判定插值效果的標準,得出如下結論:通過高斯權重法與結合逐步訂正的高斯權重法的對比,說明結合逐步訂正方案的高斯權重法可大大提高地面日氣溫的插值精度;在高斯權重法中加入海拔影響項可以反映出溫度隨地形高度的變化趨勢,同時也能較大地提高地面日氣溫的空間插值精度,說明在地形復雜的區域,地形影響在插值精度中是不可忽略的;對于高斯權重法的兩種改進方案得到的地面日氣溫分布圖都能很好地反映出表面大氣氣溫隨地形高度的變化趨勢。
  4. All the transmission lines of west - east electricity transmitting project are inevitable to crossing the high altitude and icing areas. for the reducing of the air pressure and the absolute humidity, the electricity strength of insulators will drop obviously. therefore, it must be considered the effect on the insulators " flashover voltage caused by the change of altitude and ice when the insulation cooperation of transmission lines are being designed

    「西電東送」工程的所有輸電線路都不可避免的要經過高海拔和覆冰地區,由於大氣壓力和絕對濕度的降低會使絕緣子的電氣強度顯著下降,因此在進行輸電線路的絕緣配合設計時必須考慮到海拔高度和覆冰的變化對絕緣子的閃絡電壓影響。
  5. ( 三 ) under the dynamic load of the explosion, the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0. 3hz, the acceleration of the slopes top gets the maximum ; so 0. 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform, when the relative altitude is up to 45m, the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m, the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration, at the top of the slope, the acceleration of horizon become larger and larger ; at the middle part of the slope, it becomes smaller ; ( 4 ) when the explosion velocity of is much little, the shallow part destruction is the primary deformation of the slope

    (三)採用模態疊加法針對爆破動力作用,進行邊坡的動力響應分析,得出了以下結論: ( 1 )振動頻率為0 . 3hz時,坡面頂部水平向加速度峰值最大;綜合考慮,可認為該邊坡的自振頻率為0 . 3hz左右; ( 2 )地形對爆破地振動存在放大作用,研究剖面的坡面,水平向加速度及位移在地形相對高差45米左右最大,而後隨相對高差的增高而減小,相對高差為100米時,水平向位移及加速度絕對值均大於坡腳; ( 3 )強迫振動段,水平向加速度值隨時間變化的規律為:坡頂節點總的變化趨勢是越來越大,而坡體中部節點的變化趨勢是越來越小; ( 4 )當爆破振速較小時,變形破壞的形式表現為坡頂表面滑塌型。
